TOPLINE:

Patients with psoriasis had a 1.77-fold increased risk of having obstructive sleep apnea, in a study comparing patients with psoriasis with controls.

METHODOLOGY:

• Prior studies have established a link between psoriasis and obstructive sleep apnea (OSA), but some have suggested that confounders may drive the association.
• Using a case-control design, researchers analyzed data from 156,707 participants in the National Institutes of Health’s : 5140 with psoriasis and 151,567 controls.
• They used Pearson’s x 2 test to compare the prevalence of OSA among cases and controls, logistic regression to calculate odds ratios (ORs) in multivariable analysis, and two-sided t-tests to evaluate the significance between continuous variables.

TAKEAWAY:

• Compared with controls, patients with psoriasis were older (a mean of 62.4 vs 57.3 years, respectively), more likely to be White (86.1% vs 70.6%), reported higher annual household incomes (59.9% vs 52.6%), and were more likely to smoke (48.2% vs 43.4%).
• The rate of OSA was significantly higher among patients with psoriasis compared with controls (29.3% vs 17.1%; P < .001).
• On unadjusted multivariable logistic regression controlling for age, gender, and race, psoriasis was significantly associated with OSA (OR, 1.77, 95% CI, 1.66 - 1.89; P < .001).
• Psoriasis was also significantly associated with OSA in the adjusted model controlling for age, gender, race, BMI, and smoking status (OR, 1.66, 95% CI, 1.55 - 1.77; P < .001) and in the adjusted model controlling for age, gender, race, BMI, smoking status, type 2 diabetes, congestive heart failure, hypertension, history of myocardial infarction, angina, and peripheral artery disease (OR, 1.45, 95% CI, 1.35 - 1.55; P <.001).

IN PRACTICE:

“This study further substantiates the association between psoriasis and OSA, reinforcing the importance of evaluation for OSA when clinically appropriate given that both psoriasis and OSA contribute to adverse health outcomes,” the authors conclude.

SAN DIEGO — Women with autoimmune skin diseases are at increased risk of adverse pregnancy outcomes and may benefit from multidisciplinary care with maternal-fetal medicine specialists, results from a large case-control study suggest.

Patients with systemic autoimmune conditions are known to have an increased risk for adverse pregnancy outcomes, “but we weren’t sure if that was the case for patients with autoimmune skin conditions,” presenting study author Heejo Keum, a fourth-year medical student at the University of Texas Southwestern Medical Center, Dallas, said in an interview during a poster session at the American College of Rheumatology (ACR) 2023 annual meeting. “There are case reports or nationwide population-based studies on patients with alopecia areata and vitiligo, but those were outside of the US, so we wanted to see if these outcomes could be studied in a larger population-based study in the US.”

166124_Keum_Heejo_TX_web.JPG

Drawing from the TriNetX US Collaborative Network, a database of electronic medical records of 94 million patients in the United States, the researchers identified pregnant patients aged 15-44 years between January 1, 2016, and December 31, 2021. Cases were defined as patients diagnosed with at least one autoimmune skin disease (ASD) prior to the end of pregnancy, including alopecia areata, bullous pemphigoid, cicatricial pemphigoid, dermatitis herpetiformis, cutaneous lupus erythematosus, epidermolysis bullosa acquisita, morphea, pemphigus foliaceus, pemphigus vulgaris, vitiligo, and amyopathic DM. There were two control groups: healthy controls (those without ASDs, systemic lupus erythematosus or rheumatoid arthritis) and disease controls (those with SLE or RA). The researchers used ICD-10 codes to identify pregnancy endpoints, including live births, spontaneous abortion, and stillbirth. Patients with a history of hidradenitis suppurative were excluded from the analysis, as were those with common autoimmune disease such as Hashimoto’s thyroiditis, Grave’s disease, and type 1 diabetes.

The primary outcomes were adverse pregnancy outcomes defined as spontaneous abortion, gestational hypertension, preeclampsia/eclampsia, gestational diabetes, intrauterine growth restriction (IUGR), preterm premature rupture of membranes (PPROM), and preterm birth. The researchers used 1:1 propensity scoring to match patients with ASDs to controls by age, race, ethnicity, comorbidities, obesity, and substance use, and used odds ratio (OR) analysis with a 95% confidence interval (CI) to calculate each outcome.

Ms. Keum reported results from 3,654 women with ASDs, 3,654 healthy controls, 2,147 women with SLE, and 889 women with RA.

The three most common ASDs were vitiligo (30%), alopecia areata (30%), and cutaneous lupus erythematosus (27%). Compared with healthy controls, patients with ASDs were more likely to have spontaneous abortions (OR=1.5 [1.4-1.7], P<.001), and preeclampsia/eclampsia (OR=1.2 [1.0-1.3], P=.04). Compared with women with SLE, women with ASDs were less likely to have preeclampsia/eclampsia (OR=0.7 [0.6-0.9, P=.001); preterm birth (OR= 0.5 [0.4-0.7], P<.001); PPROM (OR=0.6 [0.4-0.9], P=.004), or an infant with IUGR (OR=0.6 [0.5-0.8], P<.001), but they were more likely to have a spontaneous abortion (OR=1.2 [1.1-1.3], P=.003). Overall, patients with ASDs had similar risks for adverse pregnancy outcomes as patients with RA.

[embed:render:related:node:263044]

“We found that patients with cutaneous lupus and vitiligo had higher rates of spontaneous abortion, which is interesting because we didn’t expect that,” Ms. Keum told this news organization. “Studies have shown that vitiligo patients might have an increased risk of pregnancy loss, so I think it’s important to have that discussion with those patients. It might benefit them to talk to a maternal-fetal medicine specialist. As for next steps, we want to look at how medication use and disease flare or disease severity play a role in APOs.”

In their poster, the researchers acknowledged limitations of the study, including the inability to verify diagnoses or assess disease severity. Also, while medication use and concomitant antiphospholipid syndrome were evaluated as risk factors for advanced pregnancy outcomes, the number of patients per group was too small for analysis.

Karl Saardi, MD, director of the inpatient dermatology service at George Washington University Hospital, Washington, who was asked to comment on the study, said that in his view, the choice of disease states included in the analysis “is a bit arbitrary.” He added that “it would have been more helpful to compare controls versus discoid lupus versus systemic lupus or controls versus amyopathic dermatomyositis versus dermatomyositis with myopathy.”

The study received funding support from the Rheumatology Research Foundation and the UT Southwestern Dean’s Research Scholar program. Neither Ms. Keum nor Dr. Saardi reported having relevant disclosures.

SAN DIEGO – In the spring of 2024, the American College of Rheumatology is expected to release guidelines to help inform the screening, monitoring, and treatment of interstitial lung disease (ILD) in people with systemic autoimmune rheumatic diseases (SARDs).

The guidelines, which were previewed during a session at the ACR’s annual meeting, will include 50 recommendations, 3 of which met criteria for a strong rating:

• For people with SARDs at increased risk of developing ILD, the authors strongly recommend against screening with surgical lung biopsy.
• For people with systemic sclerosis (SSc)-related ILD, the authors strongly recommend against glucocorticoids as a first-line ILD treatment.
• For people with SSc-related ILD progression despite an initial ILD treatment, the authors strongly recommend against using long-term glucocorticoids.

Elana J. Bernstein, MD, MSc, a rheumatologist who directs the Columbia/New York-Presbyterian Scleroderma Center, and Sindhu R. Johnson, MD, a rheumatologist who directs the Toronto Scleroderma Program at the University of Toronto, provided a sneak peek of the recommendations to attendees before anticipated publication in Arthritis & Rheumatology and Arthritis Care & Research. For now, guideline summaries for screening and monitoring and treatment are currently available, and three manuscripts are under peer review: one about screening and monitoring, one about treatment, and one about the patient panel that participated in the effort.

Pediatric patients with SARDs excluded

The guidelines’ population of interest was people 17 years of age and older who were diagnosed with SARDs with a high risk of ILD. Pediatric patients with SARDs were excluded from the endeavor, as were those with systemic lupus erythematosus, antineutrophil cytoplasmic antibody–associated vasculitis, sarcoidosis, ankylosing spondylitis, undifferentiated connective tissue disease, interstitial pneumonia with autoimmune features, and those with unclassifiable ILD.

In the realm of screening, the guideline authors conditionally recommend two screening tests for patients considered at increased risk of ILD: pulmonary function tests and high-resolution chest CT (HRCT). Pulmonary function tests should include spirometry, lung volumes, and diffusion capacity. “Office spirometry alone is insufficient,” said Dr. Johnson, who served as lead author of the guidelines. And while a HRCT scan is recommended, “some patients may present to the emergency room with acute onset shortness of breath, and they may receive a CT angiogram to screen for pulmonary embolism,” she said. “It’s important to note that CT angiograms are performed in incomplete inspiration to maximize pulmonary artery enhancement. This may produce atelectasis that may obscure or mimic ILD. As a result, CTA studies are often inadequate to screen for ILD.”

Once a patient is diagnosed with ILD, three tests are recommended for monitoring: pulmonary function testing (every 3-6 months the first year in patients with IIM and SSc, then less frequently once stable, and every 3-12 months in the first year in patients with RA, SjD, and MCTD, then less frequently once stable); ambulatory desaturation testing every 3-12 months; and HRCT as needed. Dr. Johnson noted that while that the screening of ILD lies within the realm of rheumatologists, “once a patient is diagnosed, we are encouraged to comanage these patients with pulmonologists,” she said. “Ambulatory desaturation testing is not an infrequent test in the hands of pulmonologists. This is where co-management can be helpful.” She characterized a 6-minute walk test with continuous oximetry as “insufficient and is not synonymous with ambulatory desaturation testing. Ambulatory desaturation testing includes up titration of oxygen if a patient desaturates.”

The guidelines conditionally recommend against using chest radiography, 6-minute walk test distance, ambulatory desaturation testing, and bronchoscopy for ILD screening, and there is a strong recommendation against surgical lung biopsy. “However, there are unique circumstances where these tests may be considered,” Dr. Johnson said. “For example, ambulatory desaturation testing may be helpful if a patient is unable to perform a pulmonary function test. Bronchoscopy may be used to rule out infection, sarcoidosis, lymphoma, or alveolar hemorrhage, and surgical lung biopsy may be considered if you’re trying to rule out a malignancy.”

Similarly, several tests are conditionally recommended against for the monitoring of ILD, including chest radiography, the 6-minute walk test distance, and bronchoscopy. “But there are unique circumstances where they may be considered,” she said. “The 6-minute walk test may be used if a patient is unable to perform a pulmonary function test or if they’re being assessed for lung transplantation. Bronchoscopy may be used to rule out infection or alveolar hemorrhage.”
 

Preferred treatment options described

First-line treatment recommendations for ILD were based on the best available published evidence, voting panel expertise, and patient preferences. For SSc, the preferred treatment options include mycophenolate (CellCept), tocilizumab (Actemra), or rituximab (Rituxan and biosimilars), while additional options include cyclophosphamide, nintedanib (Ofev), and azathioprine. For myositis, the preferred treatment options include mycophenolate, azathioprine, rituximab, or calcineurin inhibitors, while additional options include a Janus kinase (JAK) inhibitor or cyclophosphamide. For MCTD, the preferred treatment options include mycophenolate, azathioprine, or rituximab, while additional options include tocilizumab or cyclophosphamide. For RA and Sjögren’s, the preferred treatment options include mycophenolate, azathioprine, or rituximab, while additional options include cyclophosphamide. Dr. Johnson emphasized that there was low certainty evidence to recommend one treatment over another. “Many situations might lead a provider to choose a different option for ILD treatment, such as the presence of comorbidities or extra-pulmonary disease,” she said. “So, while our guidelines were focused on effectiveness for ILD, providers may choose therapies that will help ILD and other disease manifestations.”

The guidelines conditionally recommend a short course of glucocorticoids as a bridging therapy or for treatment of a flare of ILD in patients with myositis, MCTD, RA, and Sjögren’s. The panel strongly recommends against the use of glucocorticoids in patients with SSc due to the concern for inducing a scleroderma renal crisis. “While this may be common knowledge for rheumatologists, it may not be common knowledge for pulmonologists,” she said. “So here is an opportunity to educate our pulmonology colleagues in our consultation notes.”

The guidelines also include recommendations for progression of ILD, which was defined using the INBUILD trial criteria. Mycophenolate is conditionally recommended to be the first ILD treatment for all SARDs when progression occurs, if it wasn’t the first ILD treatment used. “If it was, then other medications that rheumatologists are used to can be considered as the next ILD treatment in the face of progression: rituximab, nintedanib, tocilizumab, and cyclophosphamide,” she said. The guidelines include a conditional recommendation against long-term glucocorticoid use in myositis, MCTD, RA, and Sjögren’s, plus a strong recommendation against long-term glucocorticoid use in SSc. Finally, there is a conditional recommendation of referral for lung transplant evaluation at the appropriate time at experienced centers.

A patient panel provided input

For the undertaking, a core team that included six rheumatologists; one pulmonologist; one thoracic radiologist; one expert on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology; and two literature review experts developed clinically relevant population, intervention, comparator, and outcomes (PICO) questions. The literature review team included 13 rheumatologists, 8 pulmonologists, and 3 methodologists. Finally, a 21-member patient panel was convened to share their values and preferences regarding screening, monitoring, and treatment of SARD-related ILD. Of these, Dr. Bernstein said that 4 were at risk for ILD and 17 had been diagnosed with ILD. Next, the literature review team conducted a systematic review and used the GRADE methodology to rate the available evidence as high, moderate, low, or very low. Then, a voting panel comprising 13 rheumatologists, 10 pulmonologists, 1 radiologist, and 3 patients from the patient panel cast votes for each PICO question and made final recommendations.

The review of evidence left the guidelines authors with 241 PICO questions, “which is a lot,” Dr. Bernstein said. “To put this in perspective, some guidelines address only 10 or 15 PICO questions. Fortunately, we had a dedicated group of experts who were up to the challenge.” Dr. Johnson emphasized that the forthcoming guidelines should not be used by insurers to mandate a specific order of prescribing. “Clinicians must retain the latitude to prescribe medications based on individual patient factors and preferences,” she said.

Dr. Bernstein disclosed that she is an adviser to, a consultant for, and has received grant or research support from Boehringer Ingelheim and has also received grant or research support from Kadmon and Pfizer. Dr. Johnson disclosed that she has received research support from the American College of Rheumatology to develop these guidelines. She has also been an investigator for trials sponsored by Bristol-Myers Squibb, Roche, and Boehringer Ingelheim and has mitigated these relevant conflicts of interest 1 year prior to the development of these guidelines, and will continue to do so for the foreseeable future.

Elana J. Bernstein, MD, MSc, a rheumatologist who directs the Columbia/New York-Presbyterian Scleroderma Center, and Sindhu R. Johnson, MD, a rheumatologist who directs the Toronto Scleroderma Program at the University of Toronto, provided a sneak peek of the recommendations to attendees before anticipated publication in Arthritis & Rheumatology and Arthritis Care & Research. For now, guideline summaries for screening and monitoring and treatment are currently available, and three manuscripts are under peer review: one about screening and monitoring, one about treatment, and one about the patient panel that participated in the effort.

Pediatric patients with SARDs excluded

The guidelines’ population of interest was people 17 years of age and older who were diagnosed with SARDs with a high risk of ILD. Pediatric patients with SARDs were excluded from the endeavor, as were those with systemic lupus erythematosus, antineutrophil cytoplasmic antibody–associated vasculitis, sarcoidosis, ankylosing spondylitis, undifferentiated connective tissue disease, interstitial pneumonia with autoimmune features, and those with unclassifiable ILD.

In the realm of screening, the guideline authors conditionally recommend two screening tests for patients considered at increased risk of ILD: pulmonary function tests and high-resolution chest CT (HRCT). Pulmonary function tests should include spirometry, lung volumes, and diffusion capacity. “Office spirometry alone is insufficient,” said Dr. Johnson, who served as lead author of the guidelines. And while a HRCT scan is recommended, “some patients may present to the emergency room with acute onset shortness of breath, and they may receive a CT angiogram to screen for pulmonary embolism,” she said. “It’s important to note that CT angiograms are performed in incomplete inspiration to maximize pulmonary artery enhancement. This may produce atelectasis that may obscure or mimic ILD. As a result, CTA studies are often inadequate to screen for ILD.”

Once a patient is diagnosed with ILD, three tests are recommended for monitoring: pulmonary function testing (every 3-6 months the first year in patients with IIM and SSc, then less frequently once stable, and every 3-12 months in the first year in patients with RA, SjD, and MCTD, then less frequently once stable); ambulatory desaturation testing every 3-12 months; and HRCT as needed. Dr. Johnson noted that while that the screening of ILD lies within the realm of rheumatologists, “once a patient is diagnosed, we are encouraged to comanage these patients with pulmonologists,” she said. “Ambulatory desaturation testing is not an infrequent test in the hands of pulmonologists. This is where co-management can be helpful.” She characterized a 6-minute walk test with continuous oximetry as “insufficient and is not synonymous with ambulatory desaturation testing. Ambulatory desaturation testing includes up titration of oxygen if a patient desaturates.”

The guidelines conditionally recommend against using chest radiography, 6-minute walk test distance, ambulatory desaturation testing, and bronchoscopy for ILD screening, and there is a strong recommendation against surgical lung biopsy. “However, there are unique circumstances where these tests may be considered,” Dr. Johnson said. “For example, ambulatory desaturation testing may be helpful if a patient is unable to perform a pulmonary function test. Bronchoscopy may be used to rule out infection, sarcoidosis, lymphoma, or alveolar hemorrhage, and surgical lung biopsy may be considered if you’re trying to rule out a malignancy.”

Similarly, several tests are conditionally recommended against for the monitoring of ILD, including chest radiography, the 6-minute walk test distance, and bronchoscopy. “But there are unique circumstances where they may be considered,” she said. “The 6-minute walk test may be used if a patient is unable to perform a pulmonary function test or if they’re being assessed for lung transplantation. Bronchoscopy may be used to rule out infection or alveolar hemorrhage.”
 

Preferred treatment options described

First-line treatment recommendations for ILD were based on the best available published evidence, voting panel expertise, and patient preferences. For SSc, the preferred treatment options include mycophenolate (CellCept), tocilizumab (Actemra), or rituximab (Rituxan and biosimilars), while additional options include cyclophosphamide, nintedanib (Ofev), and azathioprine. For myositis, the preferred treatment options include mycophenolate, azathioprine, rituximab, or calcineurin inhibitors, while additional options include a Janus kinase (JAK) inhibitor or cyclophosphamide. For MCTD, the preferred treatment options include mycophenolate, azathioprine, or rituximab, while additional options include tocilizumab or cyclophosphamide. For RA and Sjögren’s, the preferred treatment options include mycophenolate, azathioprine, or rituximab, while additional options include cyclophosphamide. Dr. Johnson emphasized that there was low certainty evidence to recommend one treatment over another. “Many situations might lead a provider to choose a different option for ILD treatment, such as the presence of comorbidities or extra-pulmonary disease,” she said. “So, while our guidelines were focused on effectiveness for ILD, providers may choose therapies that will help ILD and other disease manifestations.”

The guidelines conditionally recommend a short course of glucocorticoids as a bridging therapy or for treatment of a flare of ILD in patients with myositis, MCTD, RA, and Sjögren’s. The panel strongly recommends against the use of glucocorticoids in patients with SSc due to the concern for inducing a scleroderma renal crisis. “While this may be common knowledge for rheumatologists, it may not be common knowledge for pulmonologists,” she said. “So here is an opportunity to educate our pulmonology colleagues in our consultation notes.”

The guidelines also include recommendations for progression of ILD, which was defined using the INBUILD trial criteria. Mycophenolate is conditionally recommended to be the first ILD treatment for all SARDs when progression occurs, if it wasn’t the first ILD treatment used. “If it was, then other medications that rheumatologists are used to can be considered as the next ILD treatment in the face of progression: rituximab, nintedanib, tocilizumab, and cyclophosphamide,” she said. The guidelines include a conditional recommendation against long-term glucocorticoid use in myositis, MCTD, RA, and Sjögren’s, plus a strong recommendation against long-term glucocorticoid use in SSc. Finally, there is a conditional recommendation of referral for lung transplant evaluation at the appropriate time at experienced centers.

A patient panel provided input

For the undertaking, a core team that included six rheumatologists; one pulmonologist; one thoracic radiologist; one expert on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology; and two literature review experts developed clinically relevant population, intervention, comparator, and outcomes (PICO) questions. The literature review team included 13 rheumatologists, 8 pulmonologists, and 3 methodologists. Finally, a 21-member patient panel was convened to share their values and preferences regarding screening, monitoring, and treatment of SARD-related ILD. Of these, Dr. Bernstein said that 4 were at risk for ILD and 17 had been diagnosed with ILD. Next, the literature review team conducted a systematic review and used the GRADE methodology to rate the available evidence as high, moderate, low, or very low. Then, a voting panel comprising 13 rheumatologists, 10 pulmonologists, 1 radiologist, and 3 patients from the patient panel cast votes for each PICO question and made final recommendations.

The review of evidence left the guidelines authors with 241 PICO questions, “which is a lot,” Dr. Bernstein said. “To put this in perspective, some guidelines address only 10 or 15 PICO questions. Fortunately, we had a dedicated group of experts who were up to the challenge.” Dr. Johnson emphasized that the forthcoming guidelines should not be used by insurers to mandate a specific order of prescribing. “Clinicians must retain the latitude to prescribe medications based on individual patient factors and preferences,” she said.

Dr. Bernstein disclosed that she is an adviser to, a consultant for, and has received grant or research support from Boehringer Ingelheim and has also received grant or research support from Kadmon and Pfizer. Dr. Johnson disclosed that she has received research support from the American College of Rheumatology to develop these guidelines. She has also been an investigator for trials sponsored by Bristol-Myers Squibb, Roche, and Boehringer Ingelheim and has mitigated these relevant conflicts of interest 1 year prior to the development of these guidelines, and will continue to do so for the foreseeable future.

SAN DIEGO – In the spring of 2024, the American College of Rheumatology is expected to release guidelines to help inform the screening, monitoring, and treatment of interstitial lung disease (ILD) in people with systemic autoimmune rheumatic diseases (SARDs).

The guidelines, which were previewed during a session at the ACR’s annual meeting, will include 50 recommendations, 3 of which met criteria for a strong rating:

• For people with SARDs at increased risk of developing ILD, the authors strongly recommend against screening with surgical lung biopsy.
• For people with systemic sclerosis (SSc)-related ILD, the authors strongly recommend against glucocorticoids as a first-line ILD treatment.
• For people with SSc-related ILD progression despite an initial ILD treatment, the authors strongly recommend against using long-term glucocorticoids.

SAN DIEGO – The use of abatacept (Orencia) in individuals at risk of developing rheumatoid arthritis is feasible, results from a proof-of-concept, phase 2b study showed.

The findings are encouraging because data from at-risk cohorts have reported rates of progression to RA in excess of 50% over 24 months, Andrew Cope, MBBS, PhD, head of the Center for Rheumatic Diseases at King’s College London, said during an abstract session at the annual meeting of the American College of Rheumatology. “If we’re going to do interception trials, we need to make sure that the risk-benefit is about right, and we also need to have enough events in the placebo arm against which to compare any impact of a drug,” he said.

Cope_Andrew_UK_web.jpg

For the randomized, placebo-controlled study known as the Arthritis Prevention in the Pre-clinical Phase of RA with Abatacept (APIPPRA) trial, Dr. Cope and colleagues at 28 sites in the United Kingdom and 3 in the Netherlands set out to evaluate the feasibility, efficacy, and acceptability of abatacept therapy in subjects at high risk of developing RA and to characterize the effects of T-cell costimulation modulation on the evaluation of immune and inflammatory responses associated with anti–citrullinated protein antibody (ACPA) prior to, during, and after therapy. They enrolled male and female individuals aged 18 and older with arthralgia, considered to be inflammatory in nature, and who were either ACPA and rheumatoid factor (RF) positive, or had high-titer ACPA. The researchers excluded individuals with clinically apparent arthritis, or a history of inflammatory arthritis as assessed by a rheumatologist, as well as those with a history or current use of conventional or targeted synthetic or biologic disease-modifying antirheumatic drugs (DMARDs), or oral or parenteral use of corticosteroids. They also excluded people with comorbidities requiring treatment with immunosuppressive or immune-modulating therapy, those who had received a live vaccine in the prior 3 months, as well as those who were pregnant or breastfeeding.

Study participants were randomized 1:1 to receive 52 weekly subcutaneous injections of placebo or 125 mg abatacept and were followed for another 52 weeks. The primary endpoint was time to development of clinically apparent arthritis in at least three joints, or to fulfillment of the ACR/European Alliance of Associations for Rheumatology 2010 criteria for RA, whichever comes first, during 24 months of follow-up, with joint synovitis confirmed by ultrasound.

Dr. Cope reported results from 103 patients in the placebo arm and 110 patients in the abatacept arm. Their mean age was 49 years and 77% were female. At baseline, 73% of study participants had a power Doppler score of 0, which suggests minimal levels of active subclinical synovitis in a substantial proportion of this at-risk trial population. At 52 weeks, the researchers observed 30 events in the placebo arm (29%) and 7 in the abatacept arm (6%), while at 104 weeks, there were 38 events in the placebo arm (37%) and 27 in the abatacept arm (25%). This reflected a difference in mean arthritis-free survival time between arms of 99.2 days in favor of abatacept (P = .002).

Prespecified exploratory analysis showed that individuals with high levels of ACPA or who had an extended autoantibody profile at baseline were more likely to remain arthritis-free after abatacept therapy. “So, we’re seeing a hint here that there is an abatacept-sensitive population,” Dr. Cope said.

There were 7 serious adverse events in the abatacept group and 11 in the placebo group, including 2 deaths, 1 in each arm. None of the deaths were attributable to the study drug.

In other findings during the treatment phase, subjects in the abatacept arm, when compared to those in the placebo arm, had reduced levels of anxiety on the Hospital Anxiety Depression Scale; reduced fatigue, improved physical and emotional well-being, and improved functional well-being on the Functional Assessment of Chronic Illness Therapy-Fatigue measure; reduced sleep problems on the Symptoms in Persons at Risk of Rheumatoid Arthritis questionnaire; positive impact on work instability on the RA Work Instability Scale, and a positive impact on illness beliefs.

Based on the study findings, Dr. Cope concluded that clinical trials of RA interception are feasible, and that the rates of progression to RA are consistent with cohorts in other studies. “Abatacept reduced rates of progression to RA,” he said. “We also have data to suggest that the drug reduced subclinical inflammation as defined by ultrasound.”

One of the session moderators, Jon T. Giles, MD, MPH, associate professor of medicine at Columbia University, New York, asked Dr. Cope how he and his colleagues assessed the acceptability of abatacept. “Drug adherence is quite a good way to assess that, and we set the adherence level stringently at about 90%,” Dr. Cope said. “The nonadherence was about 26%. Getting people who don’t have disease to inject [the drug] weekly is not a trivial thing.”

Bristol-Myers Squibb funded the study. Dr. Cope disclosed that he has received grant support, consulting, and/or speakers bureau fees from GlaxoSmithKline, AbbVie, Janssen, Bristol-Myers Squibb, UCB, Galapagos, and Lilly. Many coauthors of the APIPPRA trial had financial relationships with multiple pharmaceutical companies, including Bristol-Myers Squibb. Dr. Giles disclosed that he is a consultant for AbbVie, Gilead, Lilly, Novartis, and Pfizer.

SAN DIEGO – Treatment with benralizumab (Fasenra) achieved remission at 36 and 48 weeks at rates similar to those of mepolizumab (Nucala) in a head-to-head phase 3 trial of the two drugs for patients with a relapsing or refractory case of the rare vasculitis eosinophilic granulomatosis with polyangiitis (EGPA).

Benralizumab, a monoclonal antibody from AstraZeneca that binds to the alpha chain of the interleukin (IL)-5 receptor, is indicated as an add-on maintenance treatment for patients 12 years and older with severe eosinophilic asthma but is not currently approved for EGPA. Mepolizumab is a humanized monoclonal antibody targeting IL-5 and the only approved drug for EGPA.

Peter A. Merkel, MD, presented the trial, known as MANDARA, during a late-breaking poster session at the annual meeting of the American College of Rheumatology. A total of 140 patients with EGPA received either subcutaneous benralizumab 30 mg or mepolizumab 300 mg every 4 weeks for 52 weeks. The trial, which began recruitment in late 2019, was limited to patients at least 18 years of age with relapsing/refractory EGPA that required stable use of oral glucocorticoids (OGCs) and immunosuppressive therapy for at least 4 weeks prior to randomization, and the primary endpoint was the proportion of patients who achieved remission at weeks 36 and 48. Remission was defined as a Birmingham Vasculitis Activity Score (BVAS) of 0 plus an OGC dose of no more than 4 mg/day. Secondary endpoints included rates of accrued and maintained remission, OGC use, clinical benefit and complete response, blood eosinophil counts, total BVAS, and Vascular Damage Index scores. The mean age of the 140 patients was 52 years, and 60% were women.

[embed:render:related:node:248697]

Dr. Merkel and colleagues reported that the adjusted remission rate at both weeks 36 and 48 was 59.2% for those in the benralizumab arm and 56.5% for those in the mepolizumab arm (P = .7278). The percentage of patients who achieved a BVAS of 0 was similar between the two arms (83% in the benralizumab arm vs. 84.2% for those in the mepolizumab arm; P = .8502), as was the percentage of patients on an OGC dose of up to 4 mg/day (62.1% vs. 57.9%; P = .5942). At 48-52 weeks, 86.1% of patients in the benralizumab arm achieved up to a 50% reduction in OGC use, compared with 73.9% of those in the mepolizumab arm (P = .0611), and 41.4% of patients in the benralizumab arm achieved a 100% reduction in OGC use, compared with 25.8% of those in the mepolizumab arm (P = .0406).

In findings related to safety, the top three adverse events were COVID-19 (21.4% in the benralizumab arm vs. 27.1% in the mepolizumab arm, respectively), headache (17.1% vs. 15.7%), and arthralgia (17.1% vs. 11.4%).

“We were pleased with the findings because they met our expectations,” Dr. Merkel, chief of rheumatology and professor of medicine and epidemiology at the University of Pennsylvania, Philadelphia, said in an interview. “The hypothesis was that these two drugs would be equivalent and safe. The implication for patients is that they’ll have another treatment option for EGPA, which is an underrecognized disease with need for more effective treatments. I anticipate that the drug will be approved for use in EGPA, providing another option for treating this complicated multisystem eosinophilic-associated disease. Having more options for our biologic therapies is good.”

He characterized the retention of patients in MANDARA as “remarkable, despite the COVID-19 pandemic. Patients with rare diseases are quite dedicated to helping conduct research. They know that their disease is not common and that they could help others.”

The study was sponsored and funded by AstraZeneca. Dr. Merkel disclosed that he has received consulting fees and research support from many pharmaceutical companies, including AstraZeneca.

SAN DIEGO – Treatment with benralizumab (Fasenra) achieved remission at 36 and 48 weeks at rates similar to those of mepolizumab (Nucala) in a head-to-head phase 3 trial of the two drugs for patients with a relapsing or refractory case of the rare vasculitis eosinophilic granulomatosis with polyangiitis (EGPA).

SAN DIEGO – Patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) who start a tumor necrosis factor inhibitor (TNFi) appear to have rates of survival and respiratory-related hospitalization similar to those initiating a non-TNFi biologic disease-modifying antirheumatic drug (bDMARD) or Janus kinase inhibitor (JAKi), results from a large pharmacoepidemiologic study show.

“These results challenge some of the findings in prior literature that perhaps TNFi should be avoided in RA-ILD,” lead study investigator Bryant R. England, MD, PhD,  said in an interview. The findings were presented during a plenary session at the American College of Rheumatology annual meeting.

Dr. England, associate professor of rheumatology and immunology at the University of Nebraska Medical Center, Omaha, said that while RA-ILD carries a poor prognosis, a paucity of evidence exists on the effectiveness and safety of disease-modifying therapies in this population.

It’s a pleasant surprise “to see that the investigators were unable to demonstrate a significant difference in the risk of respiratory hospitalization or death between people with RA-ILD initiating non-TNFi/JAKi versus TNFi. Here is a unique situation where a so called ‘negative’ study contributes important information. This study provides needed safety data, as they were unable to show that TNFi results in worsening of severe RA-ILD outcomes,” Sindhu R. Johnson, MD, PhD, professor of medicine at the University of Toronto, said when asked for comment on the study.

“While this study does not address the use of these medications for the treatment of RA-ILD, these data suggest that TNFi may remain a treatment option for articular disease in people with RA-ILD,” said Dr. Johnson, who was not involved with the study.

For the study, Dr. England and colleagues drew from Veterans Health Administration data between 2006 and 2018 to identify patients with RA-ILD initiating TNFi or non-TNFi biologic/JAKi for the first time. Those who received ILD-focused therapies such as mycophenolate and antifibrotics were excluded from the analysis.

The researchers used validated administrative algorithms requiring multiple RA and ILD diagnostic codes to identify RA-ILD and used 1:1 propensity score matching to compare TNFi and non-TNFi biologic/JAKi factors such as health care use, comorbidities, and several RA-ILD factors, such as pretreatment forced vital capacity, obtained from electronic health records and administrative data. The primary outcome was a composite of time to respiratory-related hospitalization or death using Cox regression models.

Dr. England reported findings from 237 TNFi initiators and 237 non-TNFi/JAKi initiators. Their mean age was 68 years and 92% were male. After matching, the mean standardized differences of variables in the propensity score model improved, but a few variables remained slightly imbalanced, such as two markers of inflammation, inhaled corticosteroid use, and body mass index. The most frequently prescribed TNFi drugs were adalimumab (51%) and etanercept (37%), and the most frequently prescribed non-TNFi/JAKi drugs were rituximab (53%) and abatacept (28%).

The researchers observed no significant difference in the primary outcome between non-TNFi/JAKi and TNFi initiators (adjusted hazard ratio [aHR], 1.22; 95% confidence interval [CI], 0.92-1.60). They also observed no significant differences in respiratory hospitalization, all-cause mortality, or respiratory-related death at 1 and 3 years. In sensitivity analyses with modified cohort eligibility requirements, no significant differences in outcomes were observed between non-TNFi/JAKi and TNFi initiators.

During his presentation at the meeting, Dr. England posed the question: Are TNFi drugs safe to be used in RA-ILD?

“The answer is: It’s complex,” he said. “Our findings don’t suggest that we should be systematically avoiding TNFis with every single person with RA-ILD. But that’s different than whether there are specific subpopulations of RA-ILD for which the choice of these therapies may differ. Unfortunately, we could not address that in this study. We also could not address whether TNFis have efficacy at stopping, slowing, or reversing progression of the ILD itself. This calls for us as a field to gather together and pursue clinical trials to try to generate robust evidence that can guide these important clinical decisions that we’re making with our patients.”

He acknowledged certain limitations of the analysis, including its observational design. “So, despite best efforts to minimize bias with pharmacoepidemiologic designs and approaches, there could still be confounding and selection,” he said. “Additionally, RA-ILD is a heterogeneous disease characterized by different patterns and trajectories. While we did account for several RA- and ILD-related factors, we could not account for all heterogeneity in RA-ILD.”

When asked for comment on the study, session moderator Janet Pope, MD, MPH, professor of medicine in the division of rheumatology at the University of Western Ontario, London, said that the study findings surprised her.

Pope_Janet_Canada_web.jpg

“Sometimes RA patients on TNFis were thought to have more new or worsening ILD vs. [those on] non-TNFi bDMARDs, but most [data were] from older studies where TNFis were used as initial bDMARD in sicker patients,” she told this news organization. “So, data were confounded previously. Even in this study, there may have been channeling bias as it was not a randomized controlled trial. We need a definitive randomized controlled trial to answer this question of what the most optimal therapy for RA-ILD is.”

Dr. England reports receiving consulting fees and research support from Boehringer Ingelheim, and several coauthors reported financial relationships from various pharmaceutical companies and medical publishers. Dr. Johnson reports no relevant financial relationships. Dr. Pope reports being a consultant for several pharmaceutical companies. She has received grant/research support from AbbVie/Abbott and Eli Lilly and is an adviser for Boehringer Ingelheim.

SAN DIEGO – Pregnancy in patients with vasculitis had a higher risk for preterm delivery and preeclampsia/eclampsia – especially those with small-vessel vasculitis – compared with the general obstetric population, in a large analysis of administrative claims data presented at the American College of Rheumatology annual meeting.

“We suspect that there is a relationship between the increased risk of these serious hypertensive disorders and preterm delivery, given the higher risk of medically indicated preterm delivery,” one the of the study authors, Audra Horomanski, MD, said in an interview prior to her presentation in a plenary session at the meeting.

Limited data exist on the risks of pregnancy in patients with systemic vasculitis, according to Dr. Horomanski, a rheumatologist who directs the Stanford Vasculitis Clinic at Stanford (Calif.) University. “The majority of what we do know comes from relatively small cohort studies,” she said. “This is the first U.S., nationwide database study looking at the risk of preterm delivery and other adverse pregnancy outcomes.”

TOPLINE:

More than half of Mohs surgeons report at least one sharps injury in the past year, mostly self-inflicted, survey finds.

METHODOLOGY:

• Data on the incidence of sharps injuries among dermatologic surgeons is limited.
• In a cross-sectional analysis of anonymous survey responses from members of the American College of , researchers aimed to determine the incidence and types of sharps injuries among Mohs surgeons.
• The researchers used descriptive statistics for continuous and nominal variables (percentage and frequencies) to report survey data and Fisher exact or chi-square analysis of categorical variables to obtain P values.

TAKEAWAY:

• Of the 60 survey respondents, more than half (56.7%) were from single-specialty group practices, 26.6% were from academic practices, and fewer than half (43.3%) had been in practice for 15 or more years.
• In the past year, 56.7% of respondents experienced at least one sharps injury. Of these, 14.7% involved exposure to a blood-borne pathogen, which translated into an annual exposure risk of 7.6% for any given Mohs surgeon.
• The top two types of sharps injuries were self-inflicted suture needlestick (76.5%) and other types of self-inflicted needlestick injuries (26.5%).
• Of respondents who sustained a sharps injury, 44.1% did not report them, while 95% of all survey respondents said they had access to postexposure prophylaxis/protocols at their workplace.
• The researchers determined that the average annual rate of sharps injury was 0.87.

IN PRACTICE:

• “In best practices to prevent sharps injuries, the authors recommend that a standardized sharps handling protocol be developed and disseminated for dermatologic surgeons and their staff,” the researchers wrote.

STUDY DETAILS:

• Faezeh Talebi-Liasi, MD, and Jesse M. Lewin, MD, department of dermatology, Icahn School of Medicine at Mount Sinai, New York, conducted the research. The study was published in Dermatologic Surgery.

LIMITATIONS:

• The study’s cross-sectional observational design and small sample size was skewed toward single-specialty and academic practices.

DISCLOSURES:

• The authors reported having no relevant financial disclosures.

TOPLINE:

Incipient ulceration in primary cutaneous melanoma may represent a more biologically aggressive disease population than truly nonulcerated tumors.

METHODOLOGY:

• The final cohort included 40 cases of incipient ulceration that were matched 1:2 with 80 nonulcerated controls and 80 ulcerated controls.
• The prognostic significance of incipient ulceration in cutaneous melanoma is unclear.
• Current American Joint Committee on Cancer (AJCC) guidelines classify incipient ulceration as nonulcerated.
• In a retrospective case-control study, researchers drew from the Melanoma Institute Australia database to identify resected primary cutaneous melanomas diagnosed between 2005 and 2015 that had slides available at Royal Prince Alfred Hospital in Sydney and a Breslow thickness greater than 0 mm.
• Clinical outcomes compared between cases and controls were recurrence-free survival (RFS), melanoma-specific survival (MSS), and overall survival (OS).

TAKEAWAY:

• The median Breslow depth was 2.8 mm for incipient cases, compared with 1.0 mm for nonulcerated melanomas and 5.3 mm for ulcerated melanomas, while the median tumor mitotic rate was 5.0 per mm² for incipient cases, compared with 1 per mm² in nonulcerated controls and 9 per mm² in ulcerated controls.
• On univariable analyses, compared with patients with incipiently ulcerated cases, patients with nonulcerated tumors had significantly better OS (hazard ratio [HR], 0.49) and RFS (HR, 0.37), while patients with ulcerated tumors showed worse RFS (HR, 1.67).
• On multivariable analyses, no differences in survival outcomes were observed, perhaps due to the moderate number of incipient ulceration cases included in the study, the authors wrote.

IN PRACTICE:

“Future editions of the AJCC staging system should consider acknowledging this interpretive challenge and provide guidance on how primary melanomas with incipient ulceration should be classified,” the researchers wrote.

Richard A. Scolyer, MD, a pathologist at Royal Prince Alfred Hospital, Camperdown, Australia, is the senior author on the study, which was published online in JAMA Dermatology.

LIMITATIONS:

Limitations of the study include its retrospective design and the relatively small number of cases that met criteria for inclusion.

SAN DIEGO – Pregnant women with anti-SSA/Ro autoantibodies at titer levels of less than 1,000 ELISA units per mL are at minimal to no risk for fetal atrioventricular (AV) block and may be able to forgo traditional echocardiographic heart rhythm monitoring, results from an ongoing, prospective, multicenter trial demonstrated.

However, pregnant patients with higher titer antibodies seem to be at greatest risk for fetal AV block and may benefit from ambulatory fetal heart rhythm monitoring (FHRM), which can detect emergent AV block, according to the study findings. The findings were published online in Arthritis & Rheumatology and will be presented Nov. 13 at the American College of Rheumatology (ACR) 2023 Annual Meeting by Jill P. Buyon, MD, a rheumatologist who directs the division of rheumatology and the Lupus Center at NYU Langone Health in New York.

“While anti-Ro antibodies have been known to be associated with AV block for decades, it has become increasingly clear that antibody titers matter,” Dr. Buyon said in an interview.

For the investigation, which is the largest of its kind, researchers at 22 sites drew from the large multiracial national study of pregnant women, Surveillance To Prevent AV Block Likely to Occur Quickly (STOP BLOQ), to address the impact of anti-Ro titers and use of frequent ambulatory FHRM on outcomes in women with no previously affected children and those at risk for recurrence. Monitoring occurred during the second trimester of pregnancy (from 17 weeks through 26 weeks) and consisted of daily fetal home testing by mothers using handheld, commercially available Doppler devices.

These were followed up by weekly or biweekly echocardiograms, and ultrasound tests to evaluate fetal heart rhythm and function, as well as to show any structural problems. Three times per day, the pregnant women texted the Doppler sound recordings in real time to a pediatric cardiologist, who immediately ordered an additional echocardiogram in cases of irregular or slowing fetal heart rates. If second-degree heart block was detected, drug therapy was initiated.
 

No AV block seen with low anti-Ro titers

Dr. Buyon, who led the study with Bettina Cuneo, MD, clinical scholar and professor of surgery and pediatrics at the University of Arizona in Tucson, presented findings from 413 pregnant subjects with a mean age of 33 years who finished monitoring surveillance: 152 women had low titers of both anti-Ro60 and –Ro52 (defined as < 1,000 ELISA units per mL), and 261 women with titers above the threshold for either antibody (defined as ≥ 1,000 ELISA units per mL). Of the 152 women with low titers of both anti-Ro60 and –Ro52, none of the pregnancies past 26 weeks resulted in AV block. Of the 261 women with titers above the threshold for either antibody, 10 of the pregnancies resulted in AV block (3.8%). The incidence of AV block increased with higher antibody titer levels, reaching 7.7% for those in the top quartile for anti–60-kD SSA/Ro; this increased to 27.3% in study participants with a previous child who had AV block, although numbers in this category were small.

Analysis of cumulative FHRM recordings between surveillance echocardiograms revealed that no case of second-degree or third-degree AV block was missed. In addition, 70% of AV blocks detected by FHRM were second-degree and all occurred less than 12 hours from normal FHRM and within another 45 minutes to 4.5 hours to echocardiogram. The one case of second/third-degree and two cases of third-degree AV block were diagnosed by urgent echocardiogram more than 17 to 72 hours from a previously normal FHRM episode.
 

Other factors besides high anti-Ro titer likely play a role

“STOP BLOQ nicely demonstrates that low titer is associated with a very low risk AV block, and intense monitoring may not be needed,” Dr. Buyon told this news organization. “However, high titer is not the whole answer since even women with the very highest titers can have healthy babies. This report also shows that titers stay constant through pregnancies in the same mother, whether there is the complication of AV block or not. This suggests other factors contribute to AV block.”

She added that FHRM can be easily performed by the mother, but at this time is still best interpreted by a cardiologist. “FHRM detected all cases of AV block, which can happen in hours,” she said. “FHRM should decrease the need for frequent echocardiograms. Some mothers do have more difficulty in deciding whether the baby’s heart is beating irregularly. We need [to improve our teaching] and for how best to have a cardiologist or trained listener interpret. FHRM can be done by the mother but needs interpretation by a cardiologist until we develop a device which can identify abnormalities.”

She acknowledged certain limitations of the study, including the fact that a commercial test for anti-SSA/Ro antibody levels is not available to all clinicians. “Try to find a lab that measures high titer anti-Ro antibodies, but if not, then use one of the common commercial tests such as the BioPlex 2000 autoimmune panels and consider decreased surveillance if titer is < 8,” Dr. Buyon advised.

Vaneet K. Sandhu, MD, a rheumatologist with Loma Linda (Calif.) Medical Center, who was asked to comment on the work, said that the study not only justifies the limited use of FHRM in those with high titer antibodies (followed by urgent fetal echocardiography where indicated), but also risk stratification for fetal AV block.

“For years, we have recommended frequent fetal echocardiography testing in pregnant women with positive anti-SSA/Ro,” Dr. Sandhu said. “This study tells us we need to look deeper. On one hand, recognizing that low titer anti-Ro antibodies do not confer a risk of AV block is cost effective. On the other hand, while the titer of the antibody appears to contribute to fetal AV block, we need to delve deeper into additional factors contributing to fetal AV block risk in order to better navigate our surveillance methods.”

The study was supported by NIH grants from the National Institute of Child Health and Human Development and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Sandhu has disclosed no relevant financial relationships.
